TWO Australian couples have reportedly been stopped from leaving Thailand with their surrogate babies amid a crackdown on surrogacy laws in the country.

The ABC reported that the two homosexual couples were prevented from leaving Bangkok’s international airport on Thursday afternoon after Thai police ordered that no surrogate babies be allowed out of the country without a court order.

Two American couples were also stopped, the broadcaster reported.

The news comes as the South East Asia country looks to overhaul its commercial surrogacy laws following the case of a West Australian couple accused of abandoning a baby with Down syndrome.
